Why the study?
Cardiac power predicts outcomes in patients with reduced LVEF, but its prognostic significance in patients with normal EF remained unknown.
Does peak exercise cardiac power predict mortality and heart failure in patients with normal ejection fraction undergoing exercise stress echocardiography?
Does peak exercise cardiac power predict mortality and heart failure in patients with normal ejection fraction undergoing exercise stress echocardiography?
Peak exercise cardiac power provides independent prognostic information for mortality and heart failure in patients with normal ejection fraction undergoing stress echocardiography.

May refine risk stratification in normal-EF stress echo patients; supports further validation but should not yet change practice.
